I think after avoiding scammers the next group of people to avoid is the experts who goes about bringing out various predictions (my opinion though). Many if not all predictions in this market never worked, both the ones made on Bitcoin and the ones made on different altcoins, none has ever worked. I will suggest people should invest because they want to and not because someone else said it. When we invest based on our research it comes with a sense of carefulness but when we invest based on predictions there is every tendency that we might end up regretting it. About trading Stellar, it is one of my good coins and no regrets about it.
